Field Detail

listenerList

protected javax.swing.event.EventListenerList listenerList

List of ListDataListeners called for each change to the list.

Constructor Detail

AbstractListModel

public AbstractListModel()

Creates a new model instance - initialises the event listener list.

Method Detail

addListDataListener

public void addListDataListener(javax.swing.event.ListDataListener listener)

Add a listener object to this model. The listener will be called any time the set of elements in the model is changed.

Specified by:

addListDataListener in interface ListModel

Parameters:

listener - The listener to add

removeListDataListener

public void removeListDataListener(javax.swing.event.ListDataListener listener)

Add a listener object to this model. The listener will no longer be called when the set of elements in the model is changed.

Specified by:

removeListDataListener in interface ListModel

Parameters:

listener - The listener to remove

fireContentsChanged

protected void fireContentsChanged(java.lang.Object source,
                       int startIndex,
                       int endIndex)

Call ListDataListener.contentsChanged(javax.swing.event.ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.CONTENTS_CHANGED and represents a change to the data elements in the range [startIndex, endIndex] inclusive.

Parameters:

source - The source of the change, typically this

startIndex - The index of the first element which changed

endIndex - The index of the last element which changed

fireIntervalAdded

protected void fireIntervalAdded(java.lang.Object source,
                     int startIndex,
                     int endIndex)

Call ListDataListener.intervalAdded(javax.swing.event.ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.INTERVAL_ADDED and represents an addition of the data elements in the range [startIndex, endIndex] inclusive.

Parameters:

source - The source of the change, typically this

startIndex - The index of the first new element

endIndex - The index of the last new element

fireIntervalRemoved

protected void fireIntervalRemoved(java.lang.Object source,
                       int startIndex,
                       int endIndex)

Call ListDataListener.intervalRemoved(javax.swing.event.ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.INTERVAL_REMOVED and represents a removal of the data elements in the range [startIndex, endIndex] inclusive.

Parameters:

source - The source of the change, typically this

startIndex - The index of the first element removed

endIndex - The index of the last element removed

getListeners

public <T extends java.util.EventListener> T[] getListeners(java.lang.Class<T> listenerType)

Return the subset of EventListener objects found in this object's listenerList which are elements of the specified type.

Parameters:

listenerType - The type of listeners to select

Returns:

The set of listeners of the specified type

getListDataListeners

public javax.swing.event.ListDataListener[] getListDataListeners()

A synonym for getListeners(ListDataListener.class).

Returns:

The set of ListDataListeners found in the listenerList
